To al?. whom ifmcty concern'.-

Be 1t known that LGEORGE W. CROWELL,

a citizen of the United States, and a resident of Rogers Park, in thecounty of Cook and State of Illinois, have invented certain newanduseful Improvements in Machines for Adjusting the Ends in Vessels, ofwhich the following is a specification.

My invention relates to an improvement in machines forputting the upperend pieces into vessels, and more particularly into cylindrical parts,as will be hereinafter described, and

pointed out in the claims.

In the accompanying drawings, Figure 1 is a view, partly in section andpartly in eleva-l tion, of my improved machine, the operatingtreadlebeing omitted and the presser arm shown in its elevated position. Fig. 2is a detached View showing a portion of my improved machine inelevation, the presser-arm being lowered. Fig. 3 is a plan view thereof.Fig. 4 is a detached plan view of oneA arm of the lever and dog, andFig. 5 is a modication.

A represents a metal plate or platform, which is bolted or otherwisesecured to a wooden bench, B, adapted to holdthe bottles or vessel beingtreated, the said plate A being provided with ascrew-threaded opening,through which extends the upper end of the sleeve O, the latter beingformed with a shoulder, a, which ts against the under side of the plateA.Y n

To the sleeve C is connected another sleeve, D, by means of theoutwardly-curved plate E, which may be formed integral with or securedto the sleeves, as desired. In the two sleeves C D is nicely fitted arod or spindle, F,adapted to be vertically moved therein, and having re-A movably secured' to its upper end theipresserarm G, the latter beingprovided on its outer curved end with a small roller or easter, b,secured thereon by means of the screw c.

On the spindle F, between the two vertical sleeves C D, is secured thewheel I-I, in one side of which is formed arecess for containing thehead of the set-screw d, holding it station-- ary on the spindle. On theopposite side ofthe wheel is formed arecess, in which is fitted asliding dog, I, a portion of' the outer end 6o thereof being cut away,as shown at g, forniing the projecting end It.V This outer end of thedog I is preferably rounded or beveled, as shown in Figs. 3 and 4 of thedrawings, for a purpose hereinafter described. end of the dog is formeda recess, in which is fitted the coiled spring K, one end thereofbearing on the dog and the rear end bearing against the spindle F, thetendency of the spring being to constantly force the dog out- 7o wardly.To prevent the dog from being pushed out entirely, I form the elongatedslot or recess ,i in the wheel, and on the lower side of the dog formthe downwardly-projecting lug 7c, adapted, when the dog is moved longi-75 tudinally, to travel back and forth within the slot or recess t', andby striking the outer end thereof prevent the spring from forcing the.dog out ofthe wheel.

On the spindle F, above the wheel H, and 8o resting thereon,is looselyjournaled the sprocket-wheel L,.held in position by means of the collarZ, pinned to the spindle. Vith this wheel engages the drive-chain M,which is also connected with another pulley, (not shown,)v E5 throughwhich the power is derived to operate the machine.

From the under side and near the periphery of the wheel L depends one ormore lugs or pins, m,.which, when the dog is pushed 9o back toward thespindle F, passes over the Vcut-away portion'thereof, as shown in Fig. 1

but which, when the dog is forced outwardly, bears against the same, asshown in Fig.l 2,

and thereby throws the lower wheel, H, into 95 gear with the wheel L,and as the wheel II is held rigid with the spindle F the latter will berevolved therewith. p

On the under side of the plate A is found the downwardly-extending armN, to the lower roo endof which is pivoted a bell-crank lever, O, onearm, P, of v which extends downwardly In the rear and has secured to itslower end a treadle or foot-piece for throwing the parts into gear, aswill be hereinafter described, and the other arm, Q, ot' which extendshorizontally and bears on the under side of the wheel H,whicl1 latter ispreferably convex in form, as shown. The arm Q is provided with a slotor opening, a, through which the spindle F passes, and has its outerendslightlyturned up and rounded to conform to the shape of the outer endof the dog I, one corner of the outer end of said arm Q being formedwith the shoulder or stop o, against which the dog strikes.

n:Below-the arm Q, andk forming a bearing therefor, is the collar R,fitting around the spindle F, which collar is formed with convexshoulders for supporting the arm, the collar in turn being supported onthe spring S, coiled around the spindle Fand resting on the collar T,pinned to the spindle. To the arm Q is secured one end of a spring, U,the opposite end being secured to the under side of the plate A, thefunction of which spring U is to raise the arm Q to its normal positionafter being lowered.

Having now described the construction ot' my improved machine, I willproceed to set forth its operation.

'Ihe end to be inserted in the box is iirst partially inserted by handand the box then placed over the presserarm,the latter passing throughthe opening in the end, and rested on the plate V, secured to the upperend of the sleeve C, which plate may be made slightly concave for thepurpose of reducing the dialneter of the end when pressed down therein,and the said end therebyY more readily adjusted in the box, as shown inFig. 5 of the drawings. The foot is then placed on the treadle and thearm I? of the bell-crank O pushed forwardly, which operates to lower thearm Q and spindle F, the latter being guided in its vertical movementsby the sleeves C and D. By lowering` the arm Q the dog I is free to moveoutwardly, whereby, through the intervention of the pin m, the wheel isthrown into gear with the wheel L and the spindle F and arm G rotated.By lowering the spindle and presser-arm and rotating the same, the endo' of the box s is pressed into place and with great accuracy, theroller b ou the arm traveling around on the same and pressing it equallyon all sides until it rests iiat on the plate V. If desired, the rollerZ) may have a spring placed behind it, in order that the roller may havea slight play on the arm to compensate for any irregularities in theshape of the box. Again, if desired, the plate V may be so arranged asto be capable ot' vertical adjustment, which would allow the end to beinserted at any point within the vessel. By inserting the spring Sbetween the bearing R and collar I, the arm Q, when lowered, will giveslightly and will not impart a sudden jar to the foot of the operator,which would otherwise be the case. Again, by virtue of the elasticity ofthe spring S, the spinsoon as the bell-crank is relieved ofthe pressureof the foot, the arm Q, by virtue of the spring U, is raised and the dogI brought in contact with the outer end thereof and forced inwardlyuntil it strikes the shoulder o, whereupon the pins my, as beforedescribed, will ride over the cutaway portion of the dog, and the wheelII and the spindle F thereby stopped from rotating. The arm Q, whenraised by the spring U, raises the spindle and presserarm, whereupon thebox, with the end nicely adjusted therein, may be removed.

It will be noticed that as soon as the lever and spindle are moveddownwardly a distance equal to the thickness of the outer end ofthe dogI the latter is forced outwardly and, the wheel H immediately throwninto gear and the presser-arm rotated. This arrangement allows thepresser-arm to rotate as it is being drawn down in order to graduallyset or adjust the end in the box, which, as before stated, is tirstinserted by hand in a slanting position. If desired, the lever may beallowed a little vertical play on the spindle, in order that the wheelI-I may be thrown into gear and the spindle revolved before being movedvertically.

By having the presser-arm detachably secured to the spindle, it may beremoved and others inserted to fit boxes of different diameters.

The plate E, extending from one sleeve to the other, forms a hood orshield around the sprocketwheel. and connecting mechanism and preventsthe operators clothes from bccoining caught therein.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is
